Application March 10, 1955, Serial N 493,529

8 Claims. (Cl. Z22- 479)V The present invention relates generally to thefield of liquid dispensers, and more particularly to a liquid dispenserthat is self-ventingand seals automatically. VThis application is animprovement over my co-pending application Serial No. 384,376 filed inthe United States Patent Oliice October 6, 1953, now Patent No.2,779,517, issued January 29, 1957.

The major object in devising the present invention is to provide aliquid dispenser that can be removably ai'hxed to such containers asdrums, carboys, tanks and lil-:e commercial vessels, by means of whichliquid may be discharged therefrom at a controlled rate, which dispenseris self-vented due'to the fact that a constant atmospheric pressure ismaintained thereby within the container on which it is mounted.

Another object of the invention is to supply a dispenser thatautomatically assumes and maintains a liquid seal for the container withwhich it 'is associated until application of a duid discharge force isapplied thereto.

A further object of the invention is to furnish a dis penser that allowsfor discharge of the fluid contents of an industrial container asrequired, with the contents of the container being subjected to aminimum of atmos pheric contact. Y

A still further object of the invention is to provide a dispenser thatmay be opened and closed without the use of tools, that is easy to mounton or remove from a container, and which eliminates the possibility ofinadvertent or accidental fluid discharge from the container.

Yet another object of the invention is to provide a dispenser thatpermits liquid to be freely poured from a container within a minimum Yoftime without unde sirable wasteful splashing and gurgling thereof, whichdispenser prevents any appreciable escape of volatile vapors from thefluid contents of the container on which it is mounted.

Another object of the invention is to furnish a dispenser that isideally suited for use on containers in which inammable liquids orfluids having dangerous physical characteristics are stored, due to thespring means associated with the dispenser which at all .times urges andmaintains same in closed position whereby it cannot inadvertently assumean open position without application of actuating force that must beconstantly maintained thereon to eiect a continuing flow of fluid romthe container.

A further object of the inventionis to supply a dispenser thateliminatesV the necessity of opening a vent in a container on which itis mounted in order to discharge uid therefrom.

These and other objects and advantages of the-present invention willbecome apparent from the following description of a preferred andalternate form thereof, taken in coniunction with the accompanyingdrawings illustrating those forms, in which:

Figure 7 is a vertical cross-sectional view of a second alternate formof the invention;

Figure 8 is a vertical cross-sectional View of a third alternate form ofthe device; and

Figure 9 is a vertical cross-sectional view of a fourth alternate formof the invention.

Referring now to the drawing for the general arrangement of theinvention, it will be seen that a fluid container C is provided in whicha tapped bore R is formed that is removably engaged by a threadedportion P of the dispenser D. Container C may be of any desired size orshape as long as it is adapted to be so positioned that liquid may draintherefrom through the bore R.

A uid discharge opening A is formed in threaded portion P, which openingis defined by a body shoulder B and communicates with a tubular pouringspout S. Spout S slidably supports within its contines a springloadedsleeve T which embodies a normally sealed air vent V as well as a liquidsealing member M that removably contacts Vshoulder' B. An actuatinghandle H is rigidly aixed to sleeve T, and upon application of manualforce thereon above a predetermined value, the sleeve moves inwardlyrelative to spout S whereby the Vent V is then in communication with theatmosphere and the member M displaced from shoulder B. When handle H ismoved downwardly to position Y shown in phantom line in Figure 2, andthen slightly rotated, the sleeve T can be removably locked in apredetermined longitu-dinal position relative to the spout S wherebyliquid may be discharged through spout S without gurgling, for in orderto equalize the pressure in the container relative to atmosphericpressure during liuid discharge from the container, it ows inwardlythrough vent V Without coming into contact with an oppositely movingliquid from spout Si.

ln detail, portion P and spout S are preferably fabricated as anintegral unit, and portion P includes a cylindrical plug l@ in whichthreads 12 are formed on the exterior surface thereof. A ring 14 extendsoutwardly from plug lil and is disposed above threads l2. Ring 14 has aflat under surface 16 which grips a washer 18 disposed on the uppersurface of top 2i) of the container to effect a duid-tight sealtherewith when the plug is screwed in bore R. As may be seen in Figure2, ring 14. also has a circular flange 22 extending upwardly therefrom.A number of circumferentially spaced lugs 2e are rigidly aixed to ange22 and project outwardly therefrom. Lugs 24 can be grasped manually orby means of a suitable turning tool (not shown) to screw the plug 1t)into or out of position in bore R.

Pouring spout S is formed from a rigid tubular member which extendsupwardly from plug lil, and a bore 23 is provided in tubular member 25that extends downwardly through ring 14 into plug it? to define acircular body shoulder 3@ with a counterbcre 32 of slightly largerdiameter than bore 2S. Three vertically disposed slots 34 extenddownwardly in tubular member 25 from the upper circumferential endthereof, each of which slots terminates in a relatively short horizontalextension Se that terminates in a slightly enlarged portion 36a. Thethree slots 34 which are identical in shape, are preferably spaced fromone another by Sleeve T includes a rigid tube 3S of such external Vent-V and be so situated relative to plugV lliand pouring spout S,

`asume Y Y diameter as to snugly and slidably engage the interiorsurrateY of flow of liquid from the inside of container C face oftubular member 26. Tube 38 has the handlesH4 rigidly mounted thereon.rigid arms 40 which are horizontally disposed and rigidly aflxedrto theupper exterior surface of tube 38., Three of the'arms 4) are so disposedas to extend'outgfvardlyV through slots 34and be vertically' movabletherein;` The four arms 40 are preferably formed,withenlargedyerticallydisposed end portions 49a, which' armsj(Figure 2) rigidly support ahorizontally positioned ring 42,which slidably engages theexteriorsurfaceoftube 38.

A` helical spring 44, preferably fabricated from flat In detail, handlesH are four resilient stock, is provided that is suiiciently long to at Yall times be in compression when disposed in an encircling positionabout pouringrspout S; When so situated the upper end portion 44arofspring 44 abuts against the under side of ring 42, and the lower endportion 44b thereof disposed on theupper annulus shaped surface 42a ofYplug 10 that is situated between tubular member 26 and ange 22.7

The Vlower end portion of tube 38 has Vthreads 50 formed thereon thatVengage a tapped recess 5,2 that extends downwardly from the uppersurface 54. of an' annular sealing member 56. A washer 58 formed of aresilientsheet material thatV is` impervious to the solvent action Vandthe chemical characteristics of the liquids that will'beheld incontainer. C is bonded to the surface 54 of the sealing member.

A vertically extendingT wall 60 occupies an intermediateposition .withinthe confines of tube 38, and extends the length thereof.V Wall 60subdivides the interior of tube 38 -into two longitudinally extendingpassages, the Vfirst of the passages being vent V, and the secondpassage 61 beingof somewhat larger transverse cross section than vent Vto permit an appreciable amount of liquid in container C.to flowtherethrough. l

,The upper end of tube 38 has an end piece 62 extend-V ing thereacross.The end'piece has an air inlet port 64 formed thereinY that is incommunicationwith VentY V, and au tapped Yliquid'discharge port 66'through which liquid can ilow from the ysecond passage 61. Tube 38 Yhasan elongate opening 68 formed in the lower side,k portionthereofoppositevent V, and the opening being in communication with Ythe fluid passage61. A transversely disposed bore 70 is formed inthe lower portion oftube 38, Ywitl'i the boreV establishing communication between vent V andcountei'bore 32 in Yplug 16.

The useY and operation of the preferred form of the invention isextremely simple; YWhen the dispenser is Vmounted on. a container C aspreviously explained ,in

detail, the spring 44 at all times tends to expand to move the ring 42,sleeve T, and sealing member M upwardly.

Upward movement ofrthefassembly is limited by the .Y

resilient sealing washer 58 being brought into pressure sure contact ofwasher 58 not only prevents liquid ilow- Y ing from the inside ofcontainer C to pouring spout S,

but prevents entry of air `from the atmosphere through bore 70 tocontact the liquid held in the con-,- tainer'. Y

AIt will be apparent that upon a downward force of the requiredmagnitude being exerted on handle H, the Y sleeve T, vent V, sealingmember M and sealing washer VBy moving the handle H downwardlyY untilthe arms 40 are disposed at the position Y shown in phantomy line Y inFigure 2, and then slightly rotatingthe handles, `the armsV can becausedV to be disposed in enlarged slot exten; sions 86a. The arms 40when so disposedY causethe sleeve T, vent V, member M and sealing washer58 to Y 58 are moved downwardly relative to pouring spout S. Y

, 4 n as shown in phantom line in Figure 2 that the maximum can takeplace from the invention.

A rst alternate form of the dispenserris shown inYV Figure 5. Acylindrical shell is provided thathas a plate 82 normally disposed tothe interior surface thereof and intermediatelyV situated between theends Yof the shell. Plate 82 rigidly supports a first tubular member 84that extends downwardlythrough'an opening 85 formed in a wall 88 thatdenes'thercontainer C in which the liquid is disposed. Tubular member 84is formed with an upwardly and inwardlyY extending taperedcircumferential edge portion 86. An annular liquid sealing member 88 issupplied that has an upwardly and inwardly tapered circumferential edge88a that is adapted to set against edge portion 86 and effect a liquidseal therewith. Y

Liquid sealing member 88 closes the lowerV end of a second tubularmember 90 that is slidably'mounted in 'the frst'tubular member 84.Second tubular member Y90 as may be seen in Figure 5 is formed .with acurved up-V wardly vdisposedv'portion V92A from which liquid can bedischarged.. A'longitudinally extending intermediately disposed wall 94divides` the interior of thesecond tubularV member 9,0 into an air vent96 and a liquid discharge pas# sage 98. Air is admittedinto vent 96through an inlet port 100 formed in the curved portion 92 and dischargedfrom the lower part of the vent through a discharge port 102 formed inrst tubular member 84.

. An inverted cap shaped housing 104 that includes YaV downwardlyextending side wall 106 is provided, and is axed to the exterior surfaceYof second tubular member 90 in such a manner Vthat the sidewall 106oyerlapsthe upper portion of shell 80, and a helical spring 107 jthatdownwardly therewith, andV liquid sealing edge 88a separated fromtapered'edge 86, liquid in container C' can now ow into liquid passageV98 through an opening'109 formedrin the lower portion of second tubularmember 9,0. Atmospheric airows inwardly into container C through vent 96and port 102 as liquid is discharged Vfrom the container, to equalizethe pressures betweenV the interior and exterior of the container, andthus prevent gurgling of the liquid as itis discharged lfrom spout 92.

Of course, upon the actuating force `being removed from housing 104, thespring 107 expands, and the Vedges 86 and 88a are brought together intoliquid sealing contact. In this manner, communication between liquidpassage 98, Yair vent 107, fand the interior of container C' is blockeduntil the housing 104 is again moved to an actuating position.

A second alternate form of the invention is shown in Figure 6 in whichit will be seen that a tubular liquid dischargeV memberV is provided. Anintermediately positioned valve body 122 thatrotatably supports a plug124 divides member 120 into an outwardly disposed` porf tion 120a and aninwardly situated portion120bY Portion 120a is formed Vwith a downwardlyextending `outer end 120C.' Portion 120b is provided withthreads120d onthe free end thereof.

A tubular air vent defining member 126 is positioned above liquiddischarge member 120 and follows Vthe general contour thereof.Vent-memberj 126 isY alsodivided; by valve body 122'into an outwardly.disposed portion 126a and an inwardly disposedV portion 126b, whichVlatter Vhas threads'r120dformed therein: In*V addition it will be notedthat portion 1261)v extends inwardly beyond the termination of portionb`to prevent air passing inwardly through the vent from mixing withliquid flow-V ing outwardly through the liquid discharge member.

Plug 124 has two parallel, vertically spaced, transverse bores and 132formed therein that can be concurrently brought into alignment with theinterior of portions 120H, 120b and portions 126a, 126b, respectively.Plug 124 may be rotated by means of a handle 134 rigidly athxed to theupper portion of the plug. inadvertent displacement of plug 124 from thevalve body is prevented by the use of a downwardly extending threadedrod 136 that projects through a bore in a plate 138 that covers thelower portion of valve body 122. A nut 140 engages rod 136 and abutsagainst the exterior surface of plate 138.

The second alternateV form of the invention provides a valve in which anair vent passage is formed and terminated concurrently with the openingand closing of the valve by use of handle 134. This alternate formoperates in the same manner as the preferred form, except that thecontrol valve therefor is positioned on the exterior of the liquidcontainer with which it is used.

A third alternate form of the invention is shown in Figure 7 whichdiifers from the second alternate form only in that a continuous tubularliquid discharge member 120. and tubular air vent dening member 126 isemployed therein. The outer ends of members 120', 126' are slightlycurved, and are concurrently opened and closed by pivotal movement of aconvex-concave valve member 142. Valve member 142 is provided with twolaterally separated legs 144, the inner end portions of which arepivotally supported by screws 146 rigidly aixed to liquid dischargemember 120. A handle 148 is mounted on valve member 142 that is utilizedin moving the valve member to an open or closed position.

The fourth alternate form of the invention is illustrated in Figure 8,and is particularly well adapted for use with a relatively large liquidcontainer, such as a ve gallon can or fifty gallon drum (not shown). Thetop of a container is shown in this ligure which is provided with aliquid outlet generally designated by the numeral 162. Outlet 162includes a short, cylindrical shell 164 that projects outwardly from thecircumferential edge portion of top 160 and defines a liquid outletopening 166. Shell 164 terminates at its outermost end in an annularbead 168, which shell is adapted to receive and hold a resilient ring167 within the contines thereof. A longitudinally extending first recess170 is formed on the interior surface of ring 167 that is preferably ofrectangular transverse cross section, or at least has a flatcircumferentially extending interior surface 167a.

Two oppositely disposed, longitudinally extending recesses 172 areformed on the interior surface 167a of ring 167 and preferably located90 from the rst recess 170. A combinedV pouring spout and air vent 174is provided which is slidably mounted within the confines of ring 167.This combination spout and vent 174 is preferably fabricated as anintegral unit from one of the numerous commercially available syntheticplastic materials suitable for this purpose, the selection of which isdetermined by the fact that it will not be physically or chemicallyaected by the fluids to be dispensed therethrough. It will also beseenin Figure 8 that the combined spout and vent includes an elongatetubular member 176 inV which a longitudinally extending transverse wall178 is formed that defines an air vent 180. The surface 178:1 of wall178 and the interior surface 176a of the tubular member define a bore182 through which liquid is discharged. Vent has a portion 183 thatextends beyond the end 184 of tubular member 176 and is disposed withinthe container for the same reasons previously outlined in connection ofthose forms of the invention shown in Figures 6 and 7.

As illustrated in Figure 8, tubular member 176 has a longitudinallyextending rib 177 formed on the exterior surface thereof, which ribleads to a transversely disposedy sealing ring 188 also formed on theexterior of the tubular member. Rib 177 is slidably mountedin recess 170and permits longitudinal movement only of the combination spout and airvent 174 in shell 164.

Two oppositely disposed arms 179 are pivotally supported on the exteriorsurface of tubular member 176l by pins 17911, which arms are of suchtransverse cross section as to permit slidable movement thereof wheninserted within the contines of recesses 172. Arms 179 project beyondthe end of shell 164 and are connected to opposite circumferential edgeportions of an annular cap 185. Cap 185 (Figure 8) includes an annularplate 184 from the circumferential edge of which a continuous circularside wall 187 depends to terminate on the outer end thereof in a liange18S. At least a portion of frange 188 extends inwardly and is adapted toremovably engage the inner face 199 of bead 168. Cap 185 as well as arms179 are fabricated from a plastic material which has Asorne rigidity,but is still sufficiently resilient to permit placement of the cap inthat position shown in phantom line.

When arms 179 are in alignment with and in the same plane as that of thelongitudinal axis of shell 164, the

' tubular member 1'74 can be moved inwardly suiciently to permit the cap185 to removably engage the shell as shown. When member 174 is in thesolid line posi-tion of Figure 8, cap 18S removably effects a liquid andvapor-tight seal with shell 164. Liquid cannot escape through therecesses 172 during pouring thereof, nor can air enter the confines ofthe container, for as liquid is poured from the container, ring 188abuts against the inner surface of top 160 completely obstructingcommunication between the container interior and the outer atmosphere.

When cap 185 is in a liquid sealing position on bead 168, it seals theoutwardly disposed positions of recesses 172 and prevents passage ofliquid or outside air therethrough. From the above description it willbe seen that the ring 188 serves a dual purpose; that ofV sealing theinwardly disposed ends of recesses 172 as liquid is poured or dischargedfrom the container, and that of serving as a stop to limit the maximumoutward movement of tu- 'bular member 174 relative to, shell 164. Cap185 also serves a dual purpose in that it seals the combination air ventand pouring spout 174 and prevents inadvertent movement thereof relativeto liquid outlet 152. The operation of the fourth alternate form of theinvention is the same as that of the preferred form when it is in aliquid dispensing position.

A possible variation in the fourth alternative form of the invention isto position a helical spring that is at all times under compression inan encircling position around the combined spout and air vent 174. Thelower end of the spring rests on the upper surface of the resilient ringin which the spout and vent 174 is slidably mounted. The upper end ofthe spring is affixed to the exterior surface of the spout-and-ventcombination, which spring at ali times urges it outwardly toward apouring position in substantially the same manner in which the preferredform of the invention functions. It will, of course, be realized thatthis spring-loading of the combination spout and vent oniy results inoutward movement thereof when the resilient cap is not in lockedposition on bead 156 of outlet 16?..

The fifth alternate form of the invention shown in Figure 9 isparticularly adapted for use in discharging liquid from drums or othercontainers (not shown) that `include a wall 199 in which a tapped bore1%2 is provided through which fluid is discharged. Another tapped bore(not shown) is normally provided for such containers and is usuallypositioned in that side portion of wall 193 opposite to the dischargebore 192. This secf ond tapped bore serves as an air vent during thetime iiuid is being discharged through bore 192. When liquid V194 forreasons that will be explained hereinafter.

Y Y '7 is shippedor storedin a container of this type, both tapped boresare closed by threaded plugs (not shown) that can be easily removedtherefrom by means of a socketwrehch or the like.-Y Y Y Inusing thefifth alternate form of the invention, butV Y one plug isA removed fromone of the tapped boresV 192. VThis form includes a cylindrical body 194having threads 196 formed on the exterior surface thereof that can 'becaused to removably engage the ytapped bore 192 to establishcommunication with the liquid in the container. A cylindrical support195 projects outwardly from bodyV The support is formed with acircumferentially extending groove 19511 on the interior surfaceythereof. A bore I198 extends through body 194 and support 195, in whichbore a combination liquid discharge spout and air vent generally denotedby the numeral 200 is slida'bly mounted. The combined spout and ventembodiesv a tubular member 202, a straight portion 202a of which 'isslidably mounted in bore V198, and a downwardly andrforward'ly curvedportion 202b of which at all times Vprojects out- Y side the confines ofbore Y19S. VA resilient ring 199 situated in groove 195a that slidablyengages the exterior surface of portion 202:1 eiects a duid-'tight sealtherewith.

A longitudinally and transversely disposed wall 204 is provided insidethe combined spout and` vent that divides the interior thereof into aliquid dispensing passage 206 and air vent passage 208. A cap 210 of anydesired construction closes the'inwardly disposed end of member 202.Vandextends outwardly beyond the exterior surface thereof. When the cap210 is positioned againstthe inwardly disposed edge Vof body 19.4, itserves as a stop to limit the maximum forward movement of thecombination spout and vent memberV 200.

It will be seen in Figure 9 that a transverse port 212 Y Y Vis formed inthe inwardly disposed portion of' member portion 202:1, whichportrcommunicates with passage 205. However, when the combined spout andvent 200 is in its forwardm'ost position as shown in solid line, port212 is sealed Yout ofcommunication with vthe container interior as itresides Within the confines of body 194. A relatively large opening 214,preferably Yof substantially the same area vas that of the vent passage208, is formed in member portion 202a. VThis opening 214 is sealed fromcommunication with the interior ofthe container asY it -is situatedwithin 'body 194 when the device is in the posi- -tion shown insolidline.V l The threaded body 194 has two oppositely disposed legs 194aprojecting forwardly therefrom that support pins 21'6 or other suitablemeans on which pairs of linksV 220 are pivotally mounted. A rigid ring222 is aixed or transversely formed on the combined vent and spoutportion 202a, forwardly from legs 194g, Pairs of links 224 are pivotallymounted on pins 226 projecting oujtwardly from ring 222. The free endsof links 220V and 224 .are pivotally joined by pins 22S, as may be' seenin Figure 9. The upwardly and outwardly extending linkV in each pair oflinks 224 continues 'by means of an eX- tension 224e to a position abovethe combination vent -and spout where -the extensions 224a'areV broughttogether to form a common forwardly extending handle A helical spring232 is provided that is at all times in Ycompression and encircles thecombined vent Vand spout portion 20211. The inwardlyV disposed end ofspring 232 abuts against the forward faceY of body 194, and the forwardendof the spring bears against the rear face ofV ring 222. ltrwill beapparent that with this construction the bore 212 and opening'214 are atall times maintained out of communication with the container interiorexcept when the handle 230'isV moved in a counter clockwise direction asshown. Y UponV such m'ove- Y ment of the handle, the combined spout andvent 200 is moved `inwardly into the contines of the containersufciently to bring. bore 212 and opening `214 into corn.

In order to attach a hose to the outer extremity of the combined spoutand vent 200, or to provide a resilient liquid conduit 4by'meansAoffwhich liquid may be trans-Y ferred into a particular container, atubular ,liquid` discharge member 240 is provided.
